With world-class German engineering, your Mercedes-Benz will drive smoothly for a very long time, provided that you follow a proper servicing schedule. In particular, the engine must be looked after. To this aim, here’s a run-down of crucial Mercedes-Benz engine maintenance procedures.

Maintaining Your Mercedes-Benz Engine: 6 Service Guidelines

Book Yearly Engine Tune-Ups

It’s advisable to have your entire engine examined and tuned up once a year by technicians who deeply understand Mercedes-Benz engines. By inspecting each component and making any necessary adjustments, repairs, or replacements, we’ll keep your engine running at maximum efficiency with minimal risk of costly faults.

Change the Motor Oil Biannually

Always ensure that your luxury car is using high-quality motor oil as recommended in the owner’s manual. This oil then needs to be changed at least twice a year to keep the engine’s internal parts well-lubricated. The oil filter will also need to be changed once a year or so.

Check the Coolant Monthly

All drivers should check their motor oil and coolant regularly; once a month is ideal. Although coolant usually lasts for two or more years in great shape, it can occasionally become contaminated or somehow reduced prematurely, which must be remedied at once to protect your engine from excessive heat.

Have the Cooling System Inspected

The entire cooling system should be inspected and pressure-tested once a year. It’s unwise to ever neglect the radiator, hoses, and other cooling system components.

Replace the Air Filter Once a Year

When checking the coolant and motor oil, also take a look at the air filter, checking in-between pleats for accumulating grime. This filter prevents debris from entering the engine but needs to be replaced before it clogs up; once a year is a typical interval. 

Install New Spark Plugs 

The spark plugs inside each cylinder will usually need to be replaced after 30,000 miles or every two years. If you have tougher platinum or iridium spark plugs installed, they may last longer. 

Book Routine Mercedes-Benz Engine Maintenance 

The aforementioned services should never be neglected. Even one missed oil change can lead to permanent wear inside the engine. Scheduling routine services allows you to relax, knowing the professionals have an eye on your vehicle’s health and will remind you whenever an upcoming maintenance service is due.
